The BTU content in solid fuel on the other hand can vary widely. Lignite coal which is lowest grade of coal may only have 14 million BTU's per ton, the highest quality anthracite can exceed 28 million. You can expect about 24 to 25 million BTU's per ton on average from anthracite coal.
When I was a kid in the mid-1960s, we moved to a house that had a pile of coal in the cellar—lump coal, nice big chunks with a clean cleavage and little dust. Who knows how long it had been there, perhaps 20 or 30 years. The current heating system was a fuel-oil furnace, and all trace of the coal furnace was long gone.
The coal hot water boilers from Keystoker make for a powerful heating option to use in your home, or commercial building. Using anthracite coal to burn, or oil if you purchase a dual fuel kit, this coal burning boiler can produce anywhere from 85,000 to 528,000 BTUs.
Introduction to basic information on coal fuel 1. Lignite Lignite is the lowest ranking coal with a heating value of 8,300 Btu/lb or less and a moisture content as high as 35%. And lignitic coals have a high content of volatile matter, which makes them relatively easy to ignite. What is more, Lignite has a relatively low sulfur content, it emits low amounts of SO2. 2. Bituminous coals Bituminous coals sulfur content can be relatively high. Compared to lignite, the heating value of bituminous

Coal, for instance, is a common boiler fuel. It can even be distinguished further between lumps of coal and crushed coal, with the latter kind burning more efficiently in most cases. Of course, we know that coal isn’t always the cleanest of fuels, although it has its advantages at times and remains a common source of energy for boilers.
Jan 09, 2018 · Coal Boilers. Solid fuel boilers fired with coal — like wood — are attractive for residential uses because they are inexpensive to purchase and install and fuel is cheap. But again, like wood, coal boilers produce high emissions and large amounts of waste: fly and bottom ash. And also like wood, the energy density of most coal is very low.
Gas, oil and coal fired boilers are used extensively to provide heating, hot water and steam for process applications, and in the generation of electrical power. In all cases where a fuel is being burnt, fans are used to provide combustion air, to transport exhaust gases and in some cases used to transport and deliver the fuel (coal) into the furnace.

In these pulverised coal combustion (PCC) systems, the powdered coal is blown into the combustion chamber of a boiler where it is burnt at high temperature (see diagram). The hot gases and heat energy produced converts water – in tubes lining the boiler – into steam.
Natural gas-fired boilers may run as low as 5 percent excess air. Pulverized coal-fired boilers may run with 20 percent excess air. Gas turbines runs very lean with up to 300 percent excess air. Typical values of excess air for some commonly used fuels are shown in the table below:
As the coal gets crushed by the rolling action, the hot air dries it and blows the usable fine coal powder out to be used as fuel. The powdered coal from the pulverizer is directly blown to a burner in the boiler.
The combustion efficiency increases with increased excess air - until the heat loss in the excess air is larger than the heat provided by more efficient combustion. Excess air to achieve highest possible efficiency for some common fuels: 5 - 10% for natural gas; 5 - 20% for fuel oil; 15 - 60% for coal

Jul 12, 2016 · The most common fuel types used in industrial boiler systems are as follows: Coal Most industrial coal-fired boilers run on crushed coal, which burns more efficiently than large coal clumps. Gas and Oil Gas-fired boilers operate using natural gas, most often a mix of methane, ethane, butane, pentane, or propane.
Bituminous coal is used to generate electricity and is an important fuel and raw material for making iron and steel. West Virginia, Illinois, Pennsylvania, Kentucky, and Indiana were the five main bituminous coal-producing states in 2018, together accounting for 75% of total bituminous production.
Coal Analysis for Boiler Designers – Hydrocarbon fuels are the major source of energy for power and process steam generation, and coal takes a major share in this. Boiler furnace design will depend more on fuel characteristics, and further heat transfer surface sizing will depend on furnace outlet temperature.
A Coal stoker furnace or stove controls most operations including automatically feeding the coal. They are quite similar to any conventional oil and gas units and easily operated for extended periods of time. They commonly use rice coal but may use larger sizes like buckwheat.
Fuels commonly fired in boilers include fossil, biomass, and RDFs as well as other types of fuels and fuel combinations. Coal, petroleum-based oils, and natural gas are fossil fuels commonly fired in ICI boilers. However, other forms of solid, liquid, or gaseous fuel derived from these fossil fuels are sometimes included in this category. One of these fuels, which is referred to as tire-derived fuel (TDF), consists of shredded vehicle tires. Another boiler fuel is referred to as biomass.
Pulverized fuel boiler: Coal is pulverized into a fine dust (about 0.1 mm in size), and is fed into the boiler in a stream of air. They are by far the most common boiler types for coal. These boilers can reach efficiencies of over 90% when they are well run. They can be co-fired with wood or other suitable fuels as well.

Dec 17, 2018 · Steam coal, also known as thermal coal, is suitable for electric power production. Steam coal is ground into a fine powder that burns quickly at high heats and is used in power plants to heat water in boilers that run steam turbines. It also may be used to provide space heating for homes and businesses.
Smokeless coal-based solid fuels in an open fire or solid fuel stove still give off that cosy glow that makes a room feel homely and welcoming. Some homes also have coal-fired boilers. However, the disadvantage of coal is the need to find room to store it and then move it piecemeal to the fire or boiler.
